Abstract

Oil content in the water that exceeds the threshold can pollute the environment if disposed of directly without waste treatment. This study conducted a case study of engineering waste treatment containing 1% oil using the Dissolve Air Flotation (DAF) method through coagulant and flocculant pre-treatment. The independent variable used in this study is pressure and residence time, where the pressure variable consists of 0.6, 0.8, 1, 1.2, and 1.4 bar, while the residence time variables comprised 5, 15, 30, 45, and 60 minutes. This study obtained the maximum pressure and residence time, namely at a pressure of 1.4 bar and a residence time of 60 minutes; the highest oil removal was 98.32%. Turbidity removal was 92.31% in 1% of engineering waste for engineering destruction.

Abstract

The COVID-19 pandemic has introduced significant behavioral changes driven by adopting health protocols known as the 5M measures—mask-wearing, handwashing, maintaining physical distance, limiting mobility, and avoiding crowds. This study evaluates the implementation of the 5M health protocols in Trenggalek and Bendungan Districts, representing urban and rural areas, respectively. Utilizing the Unified Theory of Acceptance and Use of Technology (UTAUT) model, modified with Clean and Healthy Behavior (PHBS) constructs, this research examines community awareness and adherence to 5M protocols. A survey involving 758 respondents from both districts was conducted during the pandemic to assess factors influencing compliance. The findings highlight that social influence through counseling, advertisements, and posters plays a pivotal role in shaping behavioral intentions related to protocol adherence. Furthermore, these intentions directly influence actual behavior, reinforcing sustained compliance with the 5M measures. Notably, urban and rural contexts demonstrated similar patterns, underscoring the universal impact of social influence regardless of geographic setting. This study concludes that strengthening community engagement and targeted social campaigns can enhance public health resilience and preparedness for future pandemics by fostering sustainable health-conscious behavior.

Abstract

The effluent discharged from the batik textile industry often contains azo compounds and organic contaminants. One method employed to address these pollutants is the Electrofenton (EF) technique. This study aims to assess the effectiveness of electrofenton in reducing both color content and COD (Chemical Oxygen Demand) in batik dyeing effluent. The Electrofenton process was conducted in batch mode, varying electrode distances at 4 cm and 6 cm, H2O2:FeSO4 molarity ratios of (10:0.05) and (10:0.1), and electric voltage strengths at 6 volts and 8 volts. The research revealed that employing an electric voltage of 8 volts, an electrode distance of 4 cm, a contact time of 120 minutes, and a Fenton dosage molarity of 10:0.05 M resulted in a remarkable removal efficiency of 97.8% with a final concentration of 103 mg/L for color content. Additionally, for COD, employing the same parameters led to a removal effectiveness of 90.1%, with a final concentration of 730 PtCo. The impact of Fenton dosage on COD removal was statistically analyzed using the t-test. The computed t-value of 3.444 surpassed the tabulated t-value of 2.776, indicating a significant influence of Fenton dosage on COD removal.
